The Name (Gain train)

The term "gaintrain" is a combination of the words "gain" and "train," with the intention of conveying the idea of building muscle through training and proper nutrition. It was coined as a catchy and concise way to describe the process of clean bulking, which involves increasing muscle mass through a caloric surplus of healthy, nutrient-dense foods.

When used as a verb, "gaintrain" can refer to the act of following a meal plan or training regimen in order to build muscle through clean bulking methods. The term "gain train" is sometimes used as an alternative spelling, with the two words being combined into a single term.
